I am about to start a complete rewiring of the 21 year old electrical system
on my trimaran
. The old system has switch and fuse panels
and I have not yet convinced myself that breakers are any better. My reasoning is that you may still have to fuse many of your circuts so all the breaker ends up doing is protecting the short run of wire to the fuse block with the fuse protecting the device and the wire leading to it. With fuses
it is easy to change the capability of a circut by just swapping out the fuse and they come in a wider assortment of sizes. I do wonder if breakers are more robust as about 25% of the old swithes are broken or intermittent.
